FASTENER.

Application filed November 5, 1913.

To all whom it may concern:

Be it known that I, GEORGE A. MAoCoR- MACK, a citizen of the UnitedStates, and resident of Boston, in the county of Suffolk and State ofMassachusetts, have invented new and useful Improvements in Fasteners,of which the following is a specification.

This invention relates to fasteners for carriage curtains and similaruses of the well known type comprising essentially a body portionadapted to be rigidly secured to a suitable support, and a rotatablymounted turn button adapted to pass through the curtain and thereafterto be turned and yieldingly locked at a right angle to said bodyportion. Fasteners of this type are usually, if not invariably, made ofbrass the turn button being made of a solid piece. Brass is an expensivematerial and the making of a solid brass turn button is a slow andlaborious process. The fasteners are sold at a. low price and themanufacturers profit is consequently very small. Therefore, aconstruction which permits of a saving in the cost of materials andlabor, is of very real importance; and it is the object of thisinvention to provide a fastener which ma be more economicallymanufactured than the fasteners of this general type heretofore made.

Referring to the drawings, which illustrate certain embodiments of myinvention,- Figure 1 is a side elevation of my improved fastener; Fig. 2is an end elevation thereof, the turn button being turned at a rightangle to the body portion; Figs. 3 and 4: are respectively a sideelevation and sectional view of a pintle; Figs. 5 and 6 are respectivelya side elevation and sectional view of the turn button shell; Figs. 7and 8 are respectively a side elevation and sectional view of a spring;Figs. 9, 10 and 11 are respectively a side elevation, sectional view andplan view of a spring plate; Figs. 12, 13 and 14 are respectively a sideelevation, sectional view and a plan view of the body portion of myimproved fastener; Figs. 15 and 16 are respectively a sectional view andplan view of my improved fastener; and Fig. 17 is a sectional view of analternative form.

A is the body portion of the fastener consisting of a hollow shellhaving a flaring base or provided with screw holes a adapted to receivescrews Y for securing the fas- Specification of Letters Patent.

tener to any suitable support, as W. The top of said body issubstantially fiat and provided with a central pintle opening (1 Theturn button instead of being formed of solid brass, according to theconstruction heretofore commonly employed, consists of a hollow shell B(Fig. 6) preferably having an inset b in its top and provided with apintle opening 6.

The turn button B is rotatably mounted upon the body A by a pintle Cwhich passes through said turn button and through the opening a into thebody A. Preferably, the said pintle C is a hollow rivet (Fig. 4) open atboth ends (Figs. 4 and 15) and hav ing a head 0 which is adapted to restwithin the inset b, the opposite end of the rivet being clenched insidethe body A. Vithin said turn button B is a substantially flat springplate D preferably of the shape shown in the drawings- (Fig. 11) andhaving a central opening 03 through which said pintle C passes. Saidplate D is further provided with sockets or depresses d and d in itsunder side preferably arranged at right angles to one another as clearlyshown in said Fig. 11. A spring E surrounding said pintle G and heldbetween said plate D and the top of the button B serves yieldingly tohold said plate against the substantially flat top of said body portionA. Upon the said top of said body A and preferably formed integraltherewith is a ridge or projection a which is adapted to rest withineither of said sockets (P, d and to cooperate therewith yieldingly tolock said turn button against rotation, as presently to be described.

The operation of the fastener is as follows: When the turn button is inwhat may be termed its normal position shown, for eX- ample, in Figs. 1and 15, the ridge or projection (A upon the top of the body A restswithin the socket d of the plate D, thus preventing rotation of thebutton and yieldingly locking it in normal position. When now the turnbutton is rotated upon its pintle to secure the flap, the plate D iselevated and held in elevated position by the projection a until thebutton reaches the position shown in Fig. 2, that is, a position atright angles to its normal position, whereupon the projection a entersthe socket (Z thus releasing the spring E and permitting it to returnthe plate D to its position against the top of the body A againyieldingly locking the turn button. To return the turn button to normalposition, it is again rotated upon its pintle in either direction,whereupon the spring plate D is again elevated and retained in elevatedposition until the projection a reenters the socket (Z thus releasingthe spring E and relocking the button in its normal position.

It will be apparent that by replacing the solid brass turn button with abutton consisting of a hollow shell in which all the moving, lockingparts are housed, the cost of materials of the fastener is very muchreduced. And not only is there a saving in the cost of material but alsoin time and labor. As I have said, the making of a solid brass turnbutton is a slow and laborious process. It takes a long time to blankthe solid button and it must then be swaged into shape and a pintle holedrilled therethrough by hand. In a fastener made according to myinvention the shells of the body and button are quickly and easily drawnand the other parts are readily made according to well understoodpractice in quantities and at small expense. This saving in materialsand labor has proved in actual practice of real commercial importance;for when it is remembered that these fasteners are made and sold by thethousands, it will be apparent that the saving in the cost of productionaccording to my invention amounts to a very large sum of money.

Fig. 15 shows the usual manner of attaching fasteners of this generaltype to a suitable support, 2'. e. by screws Y or the like which passthrough openings a in the flaring base a of the body portion A.

In Fig. 17 there is shown an alternative form of my invention whereinthe usual flaring base is omitted from the body A and the screw or otherappropriate fastening means Y is passed through the hollow pintle C andbody A into the support IV. This method of securing the fastener to itssupport not only renders it more attractive and ornamental inappearance, but also results in further economy of manufacture in thesaving of material through elimination of the usual flaring base uponthe body portion.

I claim:

1. In a fastener, the combination with a body of a turn button rotatablymounted thereon, comprising a hollow shell and a plate yieldinglymounted therein, and complementary locking members on said body and saidplate adapted yieldingly to lock said button against rotation.

2. In a fastener, the combination with a body provided with aprojection, of a turn button rotatably mounted thereon comprising ahollow shell and a plate yieldingly mounted therein provided withsockets at right angles to the center of rotation of said button, saidsockets adapted to cooperate with said projection yieldingly to locksaid button against rotation.

3. In a fastener, the combination with a body provided with aprojection, of a turn button rotatably mounted thereon comprising ahollow shell and a plate yieldingly mounted therein provided withsockets at right angles to each other, said sockets adapted to cooperatewith said projection yieldingly to lock said button against rotation.

4:. In a fastener, the combination with a body having a substantiallyflat top provided with a projection, of a turn button rotatably mountedthereon and comprising a hollow shell, a pintle passing through saidshell into said body, a plate within said button provided with socketsat right angles to each other, a spring between said plate and the topof said shell, said sockets adapted to cooperate with said projectionyieldingly to lock said button against rotation.

5. In a fastener, the combination with a body having a substantiallyfiat top provided with a projection, of a turn button rotatably mountedthereon and comprising a hollow shell, a hollow pintle open at both endspassing through said shell into said body, a plate within said buttonprovided with sockets at right angles to each other, a spring betweensaid plate and the top of said shell, said sockets adapted to cooperatewith said projection yieldingly to lock said button against rotation.
